This looks like it actually should match a script, not a language (or  
three):

   em:script(Hani) {font-style: normal; text-decoration: underline;}

Actually it's probably even more general:

   em:script(ideographic) {font-style: normal; text-decoration:  
underline;}

I wonder whether ISO 15924 should provide "macros" for types of  
scripts like pictographic -- there is Zsym already --, ideographic,  
logographic, syllabic, abjad, consonantary, abugida, alphabetic. I  
don't know whether they would be Z*** codes.
